成績平均計算（ドイツ式）

This is a grade average calculator for the German 1 to 6 scale, with per-grade weights so that exams, tests and assignments can count differently towards the average.

It is handy for tracking where you stand during a term and for working out what you need on a remaining exam to reach a target. Everything runs in your browser.

Each grade is multiplied by its weight, the results are added up, and the total is divided by the sum of the weights. Using a weight of 1 everywhere gives a plain, unweighted average.

Weights let you reflect how a course is actually marked, for example a final exam counting double a quiz, or a project counting for a third of the grade. Set them to match your school's or course's scheme.

The German scale runs from 1 (very good) to 6 (insufficient), the opposite direction to systems where higher is better, so a lower average is a better result.

The descriptor shown under the result follows the usual grade bands, so you can see at a glance whether an average lands in the good, satisfactory or sufficient range.

Once you know your current average, you can plan ahead: try different grades for an upcoming exam to see what you need to reach a target, and adjust your revision accordingly.
